Recent improvement of image fiber bundle and development of endoscope of fine diameter made use of panendoscope popular in endoscopic examination of upper GI series. Panendoscopy underwent case number in our department was 3, 111; 88.4% in total examined 3, 520 cases in last 5 years (from June, 1980 to May, 1985). On the other hand, endoscopic examination in use of side-viewing scope was underwent in about 10% of cases, almost of whose diagnosis being early gastric cancer. This fact indicates significance of endoscopy in use of side-viewing scope in endoscopic diagnosis of early gastric cancer. Visual diagnosis is important in endoscopic examination in use of front-viewing scope and examiner must observe and take a picture in excellent visual field at an optimal distance. Diagnosis of fine change such as one of early gastric cancer or stage diagnosis of peptic ulcer may depend on diagnostic ability in endoscopy of examiners. Cases with discrepancy of visual diagnosis and photodiagnosis should be, therefore, carefully judged.
